Dan Glaser, President and CEO, said: "Our quarterly results represent an excellent start to the year, continuing the strong earnings momentum the Company has achieved over the past several years. Marsh delivered underlying revenue growth across all major geographies, led by strong performance in the International division as well as sequential improvement in the U.S./Canada division. Guy Carpenter's underlying revenue growth in the quarter was driven by strong growth in its International and Global Specialty operations. The Consulting segment produced significant growth in profitability and margin expansion, led by Mercer.

Consolidated revenue in the first quarter of 2013 was $3.1 billion, an increase of 2% on both a reported and underlying basis compared with the first quarter of 2012. Underlying revenue measures the change in revenue using consistent currency exchange rates, excluding the impact of certain items, such as acquisitions, dispositions, and transfers among businesses. Operating income rose 15% to $607 million, compared with $527 million in the prior year period. Adjusted operating income, which excludes noteworthy items as presented in the attached supplemental schedules, rose 16% in the first quarter to $615 million.

As previously indicated, beginning in the first quarter of this year, Mercer has reoriented its operations around four core lines of business: Health, Retirement, Talent, and Investments. Also in the first quarter, a substantial portion of Marsh's U.S. Consumer operations was transferred to Mercer. This business represented revenue of $231 million for the full year 2012.
